“It is important to create a bathroom layout that is not only aesthetically pleasing, but first and foremost functional”


How to Improve Your Bathroom Layout

There’s plenty to think about when designing your bathroom layout. Here are some quick tips to get you started:

●     What to include: Do you really need a bathtub? Bear in mind that a shower requires 40% less floor space. What about a single or double vanity? Or a fitted or handheld bidet? Much will depend on how much space you have available.

●     Sizing: Consider using smaller fixtures and fittings. The standard depth of a vanity unit is typically 1 ft 8 inches[1]  (50 cm), but you could opt for a 1 ft (30 cm) unit to create extra floor space in tight rooms.

●     Zoning: Break your room into wet and dry zones. Your wet area should have adequate waterproofing, while your dry zone should provide enough space for towel-drying and dressing.

●     Movement and flow: You should be able to effortlessly move around your bathroom, switching from one task to another with ease. Avoid obstructions like awkward door swings. Fit an in-wall sliding door to create less of a bottleneck.

●     Positioning: Think about where to place your bathroom fittings in relation to each other. For example, it makes sense to have a mirror above your vanity, a towel rail next to your shower, and a bidet next to your toilet.

●     Toilet design: A wall-mounted model will make floor cleaning easier while also adding a modern touch. Use a concealed in-wall cistern to save on space.

●     Privacy: Consider the line of sight when opening the door and be sure to use frosted glass on any windows or doors. Think about soundproofing measures like a door sweep or in-wall insulation.

●     Accessibility: For older or less able family members, install grab bars around your shower and toilet area. You may also want to widen the doorway, install non-slip tiles, and fit an elevated toilet.

●     Storage: There are plenty of bathroom storage options available, from shelving and rails to hooks and cupboards. You can even fit a wall-mounted soap dispenser in your shower to avoid clutter.

Common Bathroom Layout Dimensions

Here are some standard dimensions to help you layout your bathroom fittings. For more accurate measurements, remember to check your specific models before finalizing any plans.


A standard tub is 2 ft 6 inches by 5 ft (76 cm by 152 cm). If you have a larger room, wider 3 ft (92 cm) models are available. You can also opt for a shorter 4 ft 6 inches (137 cm) tub to fit a smaller room.

 Soaking tubs are designed for a more relaxing, comfortable soak, so they are larger than standard tubs. You’ll need at least 3 ft by 6 ft (92 cm by 184 cm) available if you want to splash out on one of these more luxurious fixtures


A shower can be as large as you want to make it (especially when in a wet room environment). But for enclosed showers, we recommend you have at least 2 ft 6 inches square (76 cm).

For a larger shower, you can increase this to 3 ft 6 inches square (106 cm). This should make washing your body more comfortable and help avoid any elbow knocks for taller people.


2 ft 6 inches square  (76 cm) should be plenty of space to fit a standard toilet. If you have any accessibility issues, the width can be increased to 3 ft (92 cm).

Opting for a concealed cistern or wall-mounted model will save you about 1 ft in depth (30 cm).


A single vanity unit requires at least 2 ft of width by 1 ft 8 inches of depth (61 cm by 51 cm). But, if you have the space, we recommend a larger surface or even a double vanity. This will give you plenty of room to store all those bathroom accessories.

You’ll need at least 5 ft (152 cm) of width if you want to upgrade to a double vanity.


If you’re designing a bathroom with aging in mind, you’ll need to create more space. There are also additional accessories and safety features that you might want to consider.

  • Shower Seat: To make showering more comfortable
  • Grab Bars: For moving around the room safely
  • Sliding Door: To make entering the room easier and avoid awkward door swings
  • Elevated Toilet: A more practical design for less mobile people
  • Slip-Resistant Flooring: Another safety feature to stop floors from becoming a hazard when wet

All News a bathroom like in a spa hotel, but don’t know where to put the shower and where to hide the washing machine? Designer Olga Kondratova shares planning secrets

Planning a bathroom is not an easy task. How to arrange all the details functionally and ergonomically, but at the same time not forget about comfort? Designer Olga Kondratova talks about the nuances of an ideal bathroom layout.

Olga Kondratova – designer, founder of the Olga Kondratova Interior Studio. Since 2001, the design studio has successfully specialized in the interiors of apartments, townhouses, country houses and public spaces.

Rule 1: Rectangular is the ideal shape

Bathrooms come in all shapes and sizes, but the simpler the better. At the stage of planning an apartment, if possible, a rectangular room should be separated for the bathroom.

Rule 2: Shared bathroom is always better

In my opinion, it is inappropriate to place a toilet and a bath or shower in separate rooms (remember the sad options for planning decisions of Soviet panel houses). For a family with a small child, the best solution is also a combined bathroom.

Rule 3: installation is ideal for small bathrooms

Ideally, the toilet should be hidden from view. At the very least, it should be installed as far away from the entrance as possible. In a large bathroom, the toilet and shower area can be separated by a whole wall, a curtain. In a small room, use a low partition according to the height of the installation.

Another rule – always choose the second one between a toilet with a cistern and a toilet with an installation. Installation height is usually 800-1200 mm, depth – 120-250 mm. This option is much more reliable and looks better: the bathroom turns into a boudoir, powder room, where everything that guests do not need to see is hidden.

It’s also the perfect solution for tiny bathrooms where every inch of space counts. Another tip: if there is very little space in the bathroom, you can use a compact toilet model with a depth of 550 mm.

Rule 4: don’t be afraid to build a bathtub into a niche

The bathtub itself can also be a shower cabin if you install a glass door on its edge. The size of the bath in this case can be no more than 1700 × 700 mm.

Place the freestanding bathtub centrally on the wall or symmetrically with respect to another object. A great option is a bathtub built into a niche opposite a sink or window.

Rule 5: A good place for a washing machine is under the worktop

If the washing machine is located in the bathroom and not in a separate room, it must be hidden. You can embed it under a long countertop behind the facades (wooden or other material, depending on the chosen style) or close it with a curtain. A sink is also built into the countertop, decor (flowers, towels, vases) is placed on it.

Drawers and shelves can be placed under the top to store bath accessories or household chemicals. A mirror is usually needed above it, and it itself can be built into a niche – from wall to wall.

Ordinary bathroom sets do not fit well into the finished interior, and the color and material of the countertop with a sink can be identical to the materials used in the decoration of all other rooms of the apartment.

Rule 6: bulky showers are a thing of the past!

A very important tip for freestanding shower enclosures. Now they are gradually becoming a thing of the past, giving way to showers made by the “construction” method. Such a shower room is cheaper than a bulky finished cabin, it can be made of any dimensions – narrower or wider than the norm.
